Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

The self-absorption alpha range for the 5.5-MeV alpha emission in 238PuO2 was determined to be 11.7 ± 0.2 μm by measurement of the effective activity on microspkerical sources of from 150 to 250 μm diameter. A function was derived and experimentally tested which related the fractional escape of the total alpha emission to the range-radius ratio of the microspherical source. An energy distribution function was also derived for the alpha emission from a microspherical source which agreed quite well with the experimentally determined spectrum above 1 MeV. It is suggested that the derwed function provides a more accurate description of the energy region below 1 MeV than the experimental data.
